Hi
This is all new build he wants to use wire mesh to hold render I am worried about expansion and cracking therefore failure.only reason for render is to match in there is no blocks work there

If you use good quality ply and put building paper on it double line it with s/steel expanding metal and then scratch coat it then float coat ,No problems ..
